Definitions

• the present invention relates to styling compositions packaged in an aerosol device comprising a branched sulfonic polyester and a large proportion of water, as well as a styling method using such a composition.
• the branched sulfonic polyesters applied in the form of lacquers with a high alcohol content leave, after removal by brushing, the hair with a dry touch. This undesirable phenomenon is particularly visible for dyed hair.
• the US Patent 4,525,524 discloses propellant-free sprayable linear sulfonic polyester compositions which can be used for hair fixation.
• the Applicant has found that increasing the overall water content of the hair lacquers not only improves the lacquering power of the compositions obtained, but also gives the hair, after brushing, a smoother and more cosmetic feel than the known high-grade lacquers. in alcohol.
• the invention also relates to a method of capping by spraying such a styling composition, packaged in an aerosol device, on the hair.
• the liquid phase of the styling composition of the present invention contains an aqueous or aqueous-alcoholic medium, namely a mixture of water and ethanol.
• the weight ratio of the ethanol present in the liquid phase to dimethyl ether (propellant) is preferably less than or equal to 1.
• the ethanol content of the liquid phase is less than or equal to 35% by weight, preferably less than or equal to 25% by weight, and in particular less than or equal to 15% by weight.
• branched sulfonic polyesters used in the compositions of the present invention are known in the art. Their structure and synthesis are described in the documents WO 95/18191 , WO 97/08261 and WO 97/20899 .

• sulfonic function of units (c) encompasses both the sulfonic acid function (-SO 3 H) and the corresponding salified functions obtained by neutralization of the sulfonic acid function with a base, for example with an alkali metal hydroxide. .
• the sulfonic functions are preferably in the form neutralized with an organic or inorganic base.
• the units (c) are derived, for example, from dicarboxylic acids, dicarboxylic acid esters, glycols and hydroxy acids, all of them bearing at least one sulphonic group, in acidic and / or neutralized form, preferably in neutralized form. .
• the units (c) bearing at least one sulphonic function preferably represent from 2 to 15 mol% of all the monomers.

• the branched sulphonic polyesters may comprise, in addition to the four types of units (a) to (d) described above, units (e) derived from monomers comprising two different reactive functional groups, chosen, for example, from hydroxy carboxylic acids and amino acids carboxylic acids or a mixture thereof. These units (e) may represent up to 40 mol% of all the monomers (a), (b), (c), (d) and (e).
• the branched sulfonic polymers used in the present invention are preferably obtained from a monomer mixture in which the number of carboxylic acid functional equivalents is substantially equal to the number of equivalents of hydroxyl functions and amino functions. , possibly present.
• Branched sulfonic polyesters therefore have a relatively high molecular weight.
